Running ops at a tech company.

Figuring out what AI changes and what it doesn't. Writing about it weekly →

[Marc @vallver]

I started a newsletter: While You Were Working

Every Thursday — one AI development that actually matters for your business. Explored properly.

→ The Signal: what happened and why it matters
→ The So What: 2-3 things you can do THIS week
→ Quick Hits: other developments worth 30 seconds

No prompt tips. No tool listicles. Just what I'd tell another operator over coffee.

I run ops at a 1,000-person company. This is the AI newsletter I wished existed.

This is what I used via my hermes agent

I used the Magnific REST API directly with this header:

```http
x-magnific-api-key: $MAGNIFIC_API_KEY
Accept: application/json
```

No secret values were printed.

Calls made:

```http
GET $MAGNIFIC_BASE_URL/v1/resources?limit=1&order=relevance
```

Purpose: safe read-only auth check.
Result: `200 OK`.

```http
GET $MAGNIFIC_BASE_URL/v1/ai/loras
```

Purpose: check AI endpoint access without generation.
Result: `403` — not authorized.

```http
POST $MAGNIFIC_BASE_URL/v1/ai/mystic
Content-Type: application/json

{}
```

Purpose: intentionally invalid payload, to test auth/validation without starting a real generation.
Result: `403` — `Invalid wallet id`.

```http
POST $MAGNIFIC_BASE_URL/v1/ai/image-upscaler
Content-Type: application/json

{}
```

Purpose: intentionally invalid payload, to test auth/validation without starting a real upscale.
Result: `403` — `Invalid wallet id`.

Base URL used from env:

```bash
$MAGNIFIC_BASE_URL
```

Normally:

```text

```

@levelsio I worked at an office in Germany that was supposed to regulate temperature with natural air flows and had no AC. Obviously, it was like 35 degrees inside in summer and completely unbearable
